Found this going through my collection. I'm sure its just a cud but it looks like a perfect dot from every angle. Checked this site on errors and doesn't seem to have anything like this. Just thought it was a cool find. Thx

Not an error or a cud.
It is caused by a pin head sized die chip in the chrome plating on the die that expands
over time from continuous striking causing that effect.
There would be many more like this out there.

Thank you for the info.
